> Update A Group — CometChat documentation.

*In other words, as a group owner, how can I update the group details?*

You can update the existing details of the group using the `updateGroup()` method.

  <Tab title="Dart">
    ```dart theme={null}
    String GUID = "GUID";
    String groupName = "Hello Group!";
    String groupType = CometChatGroupType.public;
    String password = "";

    CometChat.updateGroup(guid: GUID,groupName: groupName,groupType: groupType,password: password ,
                          onSuccess: (Group group) {
                            debugPrint("Group Updated Successfully : $group");
                          },
                          onError: (CometChatException e) {
                            debugPrint("Group Updated failed with exception: ${e.message}");
                        });
    ```
